A man has been killed and another 10 people have been injured after a roller coaster car derailed at Disneyland theme park in Anaheim, California, local officials say. The incident happened on Disneyland's famous Big Thunder Mountain Railroad, the officials said.

"We have one fatality and 10 injured," John Nicoletti from the mayor of Anaheim's office said.

"The ride has been stabilised. Anaheim fire and police and Disneyland officials are on the scene," Mr Nicoletti said.

"At this point, all I can confirm is that there was a derailment of one of the cars while it was traversing the attraction."

The Big Thunder Mountain Railroad coaster takes park visitors on a twisting and turning ride through mineshafts and caverns of the Old West, past falling rocks and tumbling waterfalls.
